This is designed around my left elbow injury, which precludes many exercises that aggravate that joint. For example, I have eliminated b-o single arm DB rows (back), upright rows (front delts), concentration curls (biceps) and others because my elbow can't take it. But if you have no such injury, these exercises should be cycled in and out of the routine. I also de-emphasize certain exercises to suit my goals. For example, I don't want bigger legs, but I want more quad definition. And I don't do SDLs these days, because I find my hamstrings get really sore just from wide-stance squats, and hamstrings is not a goal right now anyway. Things like this are really specific to me. But the basic key in this routine is 1. To hit the muscle group twice a week and 2. to hit them differently in the latter part of the week. Of course there will be variations within a given exercise as well, like the incline BB press will be done at different angles or speeds or in drop sets or...

This is also an example of how one can work around an injury. We'll see how it goes.
